Changes

One The actual formula for spell damage is one of the biggest changes to [[combat]] in Diablo III is the way spell damage is calculated. It's been changed to work much like physical damage does; spells now come with a fairly low base damage, much like weapons, and that value is acted upon by attributes, spells, traits, and equipment bonuses, all of which factor in to the final spell damage. Equipment with +%spell damage is quite common, and mage characters will want to collect as much equipment of that type as possible, in order to improve their killing power.
